Tidal currents occur in conjunction with the rise and fall of the tide. The vertical motion of the tides near the shore causes the water to move horizontally, creating currents. When a tidal current ...

A recent fluorescent dye experiment conducted by the USGS explored the spread of pollutants in the Northeast Cape Fear ...

Berkeley engineer Evan Variano explains how underwater kites could expand the world’s renewable energy portfolio ...

Tidal currents flood and ebb with the tide, but their motion does not average to zero everywhere over a tidal cycle. The resulting net displacement of a water parcel gives rise to weak but persistent ...

This blog presents a sea generator installed to generate electricity by the use of water currents or tidal currents. It also briefly introduces a next version of tidal-flow generators and a short ...

Between Japan’s Goto Islands, the sea is doing something that is usually associated with wind farms and solar fields. Beneath the surface of the Naru Strait, a 1.1 MW turbine is drawing energy from ...

A US marine energy company has begun preparing to test a new modular tidal turbine in Massachusetts to validate the tech and bring it closer to commercial deployment. Alaska-based Sitkana highlighted ...

An Alaska-based startup is piloting a small, modular tidal turbine in Cape Cod's fast-moving currents to test its durability ahead of possible commercial deployment. NREL estimates US marine energy ...
